, obtained, when the cylinders are turned one time about. the axis of the motor.v

A further object of my invention isto bring outa construction with a full compensation of the masses being in movement.

In obtaining this result I use a construction in which the cylinders are arranged parallelly to the axis of the motor. This arrangement is known per se, however I use in a new manner special means bywhich the movement of the pistons in the cylinders is transformed into the rotating movement of the motor, a characteristic feature of my invention being the fact, that two pistons operate to drive by a body similar to atriangle a crank and that the rotating parts make only half the turns of the cranks entering fresh gases to cool the steering device.

With the above objects in view the invention consists in the construction, combination and arrangement of parts hereinafter fully described claimed and illustrated in the accompanying drawing, wherein Fig. 1 is a top view, the illustration being made partly in section in order to show the upper pair of cylinders, Fig. 2 is a similar view difier ent parts being omitted to show the under pair of cylinders, Fig. 3 is a similar view as that of Fig. 1, the pistons being all in their middle position, Fig. 4 is a side elevation partly in section showing likewise all pistons in middle position, Fig. 5 shows a front elevation of the crank gearing, Fig. 6 a front elevation taken from the right hand end, a part of the steering device being removed, Fig. 7 is an axial section of that part removed in the illustration of Fig. 6 and Fig. 8 is a front elevation of the part illustrated in Fig. 7.

On a stationary axle 5 is rotatably mounted a hollow shaft 6. Rigidly connected to this hollow shaft are a casing 7 and four cylinders 1, 2, 3, and 4. The casing 7 is therefore rotatably mounted on the axle 5. A protecting wall 20 is arranged tosurround the space between the casing and the cylinders. I V v f p In the casing 7 two wheels 9 and 9 are mounted in such a way, that they engage a gear wheel 8, which'is rigidly connected to the axle 5. The gear wheels 9 and are diametrically opposed to {each other and have half the diameter of thegear wheel 8.

Rigidly connected to the hollow shaft ,6

andarrangedradially tothe axis of thesaid shaft are two studs 11 and 11 Journalled on these studs are twotraverses or double armed levers 12and 12 .Rotatably:'connected to the ends 33' of each of the levers 12, 12 are two rods lii and 14 resp], 13 and 14 The said rods 13, 1 1, 137, 141 have their other ends journalledonpistons 16, 17,18and19. I V p The extreme ends of the. levers 1-2 and 12 form pivots for two V shaped parts and 15 The middle point of the forms the pivot for two cranks 10 and 10, which are rigidly connected to the gearwheel s and 9 The casing forms the support: for :the hub 34 of he ro ler.

The motor operatesin thefollowing manner: v Viewing Figure 1, assume that-piston 16 has just completed its compression stroke and that ignition is occurring so that the piston will be driven to the left. The pressure exerted by the explosion on the piston is transmitted by the rod 13 to the doublearmed lever 12 and over the V-shaped part 15 to the crank 10. This latter is thereby rotated and the rotation transmitted to the gear wheel 9, which rolling over the stationary wheel 8 transfers the rotating movement to the casing. This rotation is transferred by the hollow shaft6 to the cylinders The Fig. 2 shows the position of the pistons and of the cranks in the same moment, for which Fig. 1 shows the cylinders 1 and 2.

Therefore the pistons, after a half rotation of the cylinders have finished a double stroke. g

The explosion chamber of each cylinder is connected by a single channel 21, through which the gas enters and the consumed gases are expelled, to a conical body 22, the geometrical axis of which is coincident with that of the axle .5. Into this conical body position of the i is fitted gastight a hollow body '27, fixed to the axle 5.

' cape through an opening 29, Whereas the consumed gases may escape through an opening 28 and tube 28 into the atmosphere.

The body 27 and tube 28 are cooled by the entering fresh gases.

When the body 22 rotates, the four periods of suction, compression, explosion and exhaust are obtained during one rotation, each channel 21 contactingfirstly the quadrant of the body 27 with the opening 29 two unrforated quadrants and finallythe open- 1ng28. 1

It may be understood, that while I have herein described my present device in more or less detail, it may in certain instances be found desirable to modify the construction, f. i. the number of cylinders may be altered furthermore the conical steering device may be substituted by a cylindrical one without leaving the spirit of my invention. I there- I V fore reserve the privilege of resorting to all such legitimate changes or modifications therein as may be fairly embodied within the spirit and scope of the invention as claimed.

I claim: 1 1. Anvinternalcombustion engine comprising a number of cylinders havingtheir axes extending substantially parallel with a com imon center about which the cylinders are annularly disposed, pistons in said cylinders,- connecting rods coupled to said pistons,

levers having their outer ends connected to pairs of the'pistons operating in alternate relation, a shaft pins on the shaft for sup} porting the intermediate portions of the levers for pivotal movement, V-shaped parts having the free ends thereof pivoted upon the end portions of the levers, cranks coupled to the intermediate portionsof the "V parts,

pinions turnedby' said cranks and a fixed gear wheel over which said pinions are adapted to roll. V I

2. An internal combustion. engine comprising a shaft, cylinders arranged about said shaft "with their axes substantially parallel with the axis of the shaft, pistons reciprocatingjin said cylinders, connecting rods coupled'to the pistons, levers fulcrumed to rock intermediately upon said shaft and to turn with the shaft, said levers beingcoupled at their outer ends 'to pairs of the connecting rods of alternately operating pistons, a fixed gear wheel having thesame center with the shaft, pinions arranged to roll about said' gear wheel, cranks connected to 05 7 turn said 1nions, and Vshaped parts having their intermediate angledends coupled/ to said cranks and with their free end por tions pivotally enga ing the opposite ends of said levers near t e point of connection I of said connectin rods; r

In testimony t at I claim the foregoing as my invention, I have signed my name in presence of two subscribin witnesses. V a
